Service Manual

ipv6 unnumbered
Configure a tunnel interface to operate without a unique IPv6 address and select the interface from which the tunnel borrows
its address.
Syntax ipv6 unnumbered {interface-type interface-number}
To set the tunnel back to default logical address use the no ipv6 unnumbered command. If the tunnel
was previously operational, the tunnel interface is operationally down unless you also configure the tunnel
IPv4 address.
Parameters
interface-type
interface-number
Enter the interface type, followed by the type, slot and port information.
Defaults None.
Command Modes INTERFACE TUNNEL

Usage
Information
The ip unnumbered command fails in two conditions:
● If the logical ip address is configured.
● If Tunnel mode is ipv6ip (where ip address over tunnel interface is not possible).
To ping the unnumbered tunnels, the logical address route information must be present at both the ends.
NOTE: The ipv6 unnumbered command can specify an interface name that does not exist or does
not have a configured IPv6 address. The tunnel interface is not changed to operationally up until the
logical ip address is identified from one of the address family.
tunnel allow-remote
Configure an IPv4 or IPv6 address or prefix whose tunneled packets are accepted for decapsulation. If you do not configure
allow-remote entries, tunneled packets from any remote peer address is accepted.
This feature is supported on Dell Networking OS.
Syntax
tunnel allow-remote {ip-address | ipv6-address} [mask]
To delete a configured allow-remote entry use the no tunnel allow-remote command. Any specified
address/mask values must match an existing entry for the delete to succeed. If the address and mask are
not specified, this command deletes all allow-remote entries.
Parameters
ip-address Enter the source IPv4 address in A.B.C.D format.
ipv6–address Enter the source IPv6 address in X:X:X:X::X format.
mask (OPTIONAL) Enter a network mask in /prefix format (/x) or A.B.C.D to match a
range of remote addresses. The default mask is /32 for IPv4 addresses and /128
for IPv6 addresses, which match only the specified address.
Defaults If you do not configure tunnel allow remote , all traffic which is destined to tunnel source address is
decapsulated.
